Cascading

Hey all,

Some months ago I decided to poke around deeper with Hadoop, after  
having been a Nutch user for some time.

After way to much of the aforementioned poking, I decided to give my  
work a name, a home, and set it free.

You can find the results here:
http://www.cascading.org/

It seems to be useful, but that may not hold true for anyone other  
than me.

But do please give it a look and let me know what you think, if you  
are so inclined to think about it. If you use it, I would love to hear  
about that as well.

If it works for whatever you need it for, great news. If not, feel  
free to complain or contribute. It's hosted on google code and  
subsequently has a mail list and issue tracker.

The lack of comprehensive documentation is slowly being remedied.

regards,
ckw

Hey thanks!

I wasn't aware of Dryad until after I got started. But it is much  
lower level than Cascading.

That is, I believe you can implement the MapReduce model using Dryad,  
Cascading (currently) relies on the MapReduce model.

Pig and Jaql also showed up on my radar after I got started. but I see  
them as complimentary, they can participate in a Flow, or be a kind of  
Flow. that's currently undecided.

But it makes perfect sense to use Cascading to accumulate and cleanup  
data, and then hand it to Pig/Jaql for the really hard stuff, then let  
Cascading put on the finishing touches.

cheers

Hi Chris,
	Really interesting stuff. Definitely very useful for building more
complex apps. I am wondering if you were inspired at all by Microsofts Dryad
project which implements a vertex passed distributed processing platform.
Once again good job.

Thought I would briefly mention a new overview page that attempts to  
explain what Cascading does in a little more detail.

It should answer some of the questions I've received.

I'll leave you alone now.. <grin>
